Paper Abstract

The high precision optical mirrors are quite important for the modern optical system. In this paper, a novel Magnetic Medium Assistant Polishing technology and device is researched for optical finishing. The key element of the device is a designed magnetic wheel and accessorial magnetic component. The solid magnetic powder arranged with the magnetic field distribution and became a flexible polishing brush tool. The solid magnetic medium tool working with a high rolling speed and the polishing liquid with abrasive was injected to contact region of the optical surface. The magnetic powder tool is reforming with the magnetic field all the time, and this feature made the removal rate and distribution of the removal function invariable. The device is connected to the polishing machine. The fabrication experiments were completed. The distribution of the removal function is like a raindrop and asymmetry in one orientation. The removal stability of the tool was quite good and achieves 95% sameness of peak value in one hour. The primary experiments shown that the technology can be used in the practical fabrication.
